VARIABILITY OF THE DYNAMIC COEFFICIENT OF FRICTION MATERIAL IN FLEXIBLE PACKAGING

Abstract

Labels and flexible packaging on the market today take a very important role. The possibility of printing on polymeric materials of flexible packaging is diverse from OPP (Oriented Polypropylene), PVC (Polyvinyl Chloride), OPS (Oriented Polystyrene), PET (Polyethylene Terephthalate) material and all types of self-adhesive paper and foil. Special highlight are the "Shrink Sleeve" labels that meet the most demanding market challenges. Its capabilities are great, and laminated materials for packaging purposes are, for their function, both as protection and as packaging. Coefficient of friction is the value that serves to meet the standard of how the flexible packaging material will glide and move on the packaging machine. This research is focused on the optimum quality of the packaging production process to meet all the preconditions for implementation of the semifinished product packaging and to avoid difficulties and possible stoppages on the packaging machine itself.
